ed on wheels and shiftingly connected with.

the plow-beam, whereby it is not only possible to raise and lower or adjust the frame relatively to the wheels, but also to raise and lower the plow relatively to the frame and the wheels.

Generally stated, the object of my invention is to provide improved means for raising and lowering the plow, and to thereby facilitate the adjustment of the plow relatively to the frame and wheels.

A special object is to provide a construc tion and mode of operation whereby the two foot-levers may be mounted separately on two separate and distinct movable or oscillatory members, whereby one foot-lever and the member upon which it is mounted can be moved or adjusted without moving or adjusting the other member and its allotted foot-lever, and whereby a lost-motion connection may be employed between the said oscillatory parts upon which the two foot-1e vers are mounted, said lost-motion connection permitting a spring to be advantageously employed for both assisting in lifting the plow and yieldingly holding the plow in the ground, and permitting the oscillatory member upon which the depressing foot-lever is mounted to have more or less adjustment independently of the other member, for the purpose of bringing the spring from a depressing to a lifting position, and vice versa, and also permitting an adjustment of a locking element, which is rigid with the depressing lever, and which constitutes part of a locking device for locking the plow in an elevated position, without communicating any positive thrust or downward pressure to the plow through the lifting and lowering connection, which latter is preferably a jointed or toggle-like connection.

it is also an object to provide certain details and features of improvement tending to increase the general elliciency and serviceability of a foot-lifting and lowering device of this particular character.

In the accompanying drawings,Fi ure 1 is a side elevation of a wheeled-plow em odying the principles of my invention, the plow being shown in its lowered or working position; Fig. 2 is a view similar to Fig. 1, but showing the front and rear furrow-wheels and certain other parts removed, and showing the plow in elevated or partially elevated position; Fig. 3 is an enlarged plan view of my improved foot-lifting and lowering device, the parts being shown in positions corresponding to the positions in which they are shown in Fig. 1; Fig. l is a detail view of the land side of the arrangement shown in Fig. 3, and on the same scale as said figure Fig. 5 is a view similar to Fig. 4, but showing the plow-beam in an elevated position.

As thus illustrated, my wheeled-plow may comprise a plow A and a plow-beam B of any suitable known or approved form. The horizontally disposed body-frame C, carried'by the front and rear furrow-wheels D and E, and the relatively large land-side vi-heel F, can also be ofany suitable form or construction. As illustrated, the plow is swingingly or adjustably hung from the body-frame by means of bails G and G, which have their rear end portions mounted in suitable bearings g and g, carried by the body-frame, and which have their forward and transverse middle portions mounted to turn in suitable castings or bearings g and g secured to the plowbeam. Thus the forward and middle portions of these bails are adapted to swing up and down relatively to the body-frame, and to thereby serve as the shifting connections or means by which the plow is adapted to be raised and lowered relatively to the' balance of the structure. In rising, the plow moves upward and slightly to the rear; on the other hand, in descendil'ig, the plow moves downward and slightly forward. The rear furrow-wheel D is preferably in the nature of a caster-wheel, having its stem adapted. to turn in a hearing or bracket (Z secured to the rear of the l' o(lyifra1ne. Preferably, the forward furrow wheel E is of a similar character, its stem being adapted to turn in. a bearing or bracket e secured. to the righ t-lxahd side of the forward portion of the bodyframe. As illustrated, there is, however, a (.li'llerence between the forward and rear furrow wheels, inasmuch as the bearing 6 is adapted to slide up and down. upon the stem of the forward furrow wheel, thereby permitting the forward portion of the body ll'itllll) to be raised and lowered. rclath'ely to the forward. furrow wheel. his can be accoin 'ilisi'ied in any suitable manner, as, for cxiiiinple, by pivoting a hand-lever ll to the said bracket or hearing (4, and by coin'iecting this hand-lever with a casting or bracket It on the upper end of the forward furrow wheel stein, which latter can be connected with the tongue .l. ll or example, the connection between the lever ll and the bracket 7i may consist of alink It, the same being connected and arranged in any suitable or desired manner. With this provision, it is obvious that a downward swing of the lever H will raise the body-frame, while a reverse motion of the lever will lower the body-frame relatively to the forward furrow wheel.

if desired, the stems of the two furrowwheels can be connected by a rod J, in any known or approved manner, so that the rear furrow wheel stem will be held against turning while the plow is running straight ahead, but will be free to turn or caster freely 'vv'l'ien the tongue swung to one side. The landside wheel F can be mounted on the spindle or end of the crank-arm of a transversely disposed cranloaxle K, which latter is mounted for rocking or oscillatory adjust ment in hearings 7c and 7c secured to the body frame. The means for rocking this crank-axle, in the usual and wellknown manner, for the purpose of raising and lowering the body-frame or swinging or throwing the plow out of the ground, may consist of a hand-lever L, mounted. loosely upon the said crank-axle, but having a yielding or resilient connection with the said axle through the .medium of the spring Z and the arm Z, which latter is secured. rigidly to the said axle; it being observed that this spring is arranged for compression between the said. arm and a part connected. with the said lever. With this arrangement, the land-side wheel F may be said to have a yielding or resilient connec tion with the body-frame, and in this way a cushioning effect is given to said Wheel, when the locking device Z on the said lever is in. engagement with the toothed rack Z which latter is rigid with the hearing 7c. A spring Z connected between the upper end portion of the lever L and the said toothed rack Z is employed as a means for assisting in lifting or changing the level of the bodyframe.

With the provision of the two hand-levers H and L, it will be seen that both the forward furrow wheel and land side wheel can be controiied independently of each other and at will, so as to raise and lower the body frame and wing or manipulate the plow in the usual and well known manner. And at this juncture it will also be observed that the lever H is preferably provided with the lockii'ig device /if, whereby said lever can. be locked in engagement with the rack It, which latter is secured to the casting or bracket bearing e. The rear portion ol the body-Maine can be provided with the usual (.lrivcrs seat M, as shown in Figs. 1 and 2.

The features thus far described can, as stated, he of any suitable known or approved construction, inasmuch as my iI'iV(-?J).ti )ll. does not rel ate to these l'eaturcs, and a fur ther description of the same is therefore unnecessary.

It is the double foot-lever arrai'igen'ient for raisii'ig and lowering the PlOXV- 'JL-l'Hl-t is to say. for adjusting the plow relatively to the bodyfra1ne--'wl1ich constitutes my invention. This improved foot-lever arrangement with its s t ring for assistii'ig in lifting the plow and for yieldingly inaii'itaining the plow in the ground, so as to permit the plow to operate as a stone dodger, and to thereby avoid d anger of breakage by rising over obstructions, is more clearly shown by Figs. 3, 4 and 5. It will be seen that two separate and distinct oscillatory members N and O are carried by the frame, and, if so desired, are conveniently mounted upon the crank aXle K. The member N is provided with a rearwardly projecting lifting foot-lever P, which preferably swings just outside of the body-frame C.

In a similar manner, the other member 0 is provided with an upwardly and forwardly projecting depressii'ig lever Q, which can be arranged over, or substantially over, the plow-beam. It is by thus mounting the two foot-levers sep arately-that is to say, on two separate and distinct mountings, which, as is readily apparent, can, as a matter of con venience, be in the form of two separate and distinct sleeves mounted on the CI2tIll'(-&Xl0-- that the necessary relative movement or independence is secured between the two footlevers. These two structurally separate elements, N and O, are loosely mounted upon the axle K, and are thus adapted for rocking or oscillatory adjustment thereon. lhe member N is provided with an arm n, the free end of which is connected with the plowbeam by means of the link a. The arm a can be provided with an adjustable stop it, whereby the toggledike lifting and lowering device thus provided can only break joint in. an upward direction, and whereby the joint or pivotal connection may be prevented from passing below the center; and, in fact, as will hereinafter more fully appear, it is preferable that the said stop he so adjusted that the joint or pivotal connection a remains, when the plow is in. the ground, a slight distance above a line drawn from the center of the crank-axle through the axis of the pivotal point a". A

The member 0 is preferably provided with a hook 0, adapted, when the plow is raised from the ground, to engage a lug 0 on the plate 0 and at this juncture it will be ob' served that this plate 0 is preferably adjustably mounted on the plowbeam, thereby making it possible to adjust the parts accurately and in such manner as to insure the desired mode of operation. The adjustability of the said plate can be obtained by providing it with slots 35 for the attaching bolts 0 as shown more clearly in Fig. 4.

In addition to the rigid locking'projection or hook 0, the member 0 is also provided with a rigid arm 0 to the end of which is attached the bent link or connecting member 0 The other end of this link 0" is connected with one end of a heavy coil-spring R, and the other end of this spring is attached to the forward portion of the body-frame, as, for example, in the manner shown at r in Fig. 1. This spring, thus combined with the two separately mounted foot-levers, as will hereinafter more fully appear, is a combined lifting and depressing spring.

There is preferably a lost-motion connection between the two separately mounted foot-levers, said lost motion connection consisting, for example, of a notch n in the sleeve or member N, adapted to engage the tooth 0 on the other sleeve or member 0. By reason of the said notches being considerably larger than the said teeth, the foot-lever Q is capable of considerable manipulation, as willbe seen, without communicating any of the pressure or power applied to it to the plow, or to the member N.

The mode of operation is obvious. Suppose it is desired to raise the plowthat is to say, to adjust the plow relatively to the bodyframefrom the position shown in Fig. 4. This can be accomplished by simply placing the foot on the lever P, and by then pressing downward, so as to utilize this lever and the arm n as an intermediately fulcrumed lever for lifting the plow through the medium of the connecting link 72/. It will be seen, however, that with the parts in the position shown in Fig. 4, the spring R is exerting a pull above the axis of the two levers, and that at this time, therefore, the spring is serving to yieldingly hold the plow in the ground. It is evident, therefore, that should the plow strike a stone or other obstruction, in such case the connections will yield and allow the plow to automatically rise over such obstruction, thereby insuring against breakage or other danger to the structure. But now, as soon as pressure is applied, in the manner stated, to the lever P, the arm 0 is thrown downward, thereby shifting the spring to a position to pull below the axis of the two foot levers; and, by reason of. the lost motion connection between the two sleeves and the two separately mounted foot-' levers, there is a substantial lost-motion action on the part of the spring and the various connections'as soon as the point of pivotal connection between the link 0 and the arm 0 reaches a point slightly below the axis of the two levers. Thus, as soon as the spring is shifted to a point where it begins to pull slightly below the axis of the two levers,

there then takes place a free relative rotation of the two foot-levers, in order to permit the spring to automatically adjust itself and its various connections in such manner as to at once avail itself of a substantial and considerable leverage for assisting in raising'the plow. In this way, the spring and the lever P co-operate in lifting the plow-beam into the position shown in'Fig. 5. In this position, the lug 0 carried by the plow-beam engages the hook or locking projection 0, which latter is rigid with the depressing lever Q, and is thus mounted se arately and independently of the lifting fever P. The plow tends to remain locked in this position, owing to the engagement of the said hook with the lug on the plow-beam, as the plow cannot move downward without first moving forward. It is evident, therefore, that the weight of the plow is exerted in a downward and forward thrust of the lug 0 on the hook-shaped end portion of the locking projection '0; it being observed that the point of connection between the bail G and the plow-' beam, the cranked or land-side axle K and the point of engagement between the locking elements 0 and 0, are, when the plow is raised, as shown in Fig. 5, very nearly in line with each other.

Now when it is desired to lower the plow from the position shown in Fig. 5 to the position shown in Fig. 4, then the operation is as follows: Foot-pressure is applied to the lever Q in a forward direction, thereby disengag ing the locking elements 0 and 0 from each other without communicating any positive downward force or pressure upon the plow beam. As soon as the locking elements become disengaged from each other, the weight of the plow itself is then suflicient to carry it down to the ground, the lifting action of the spring on the plow being overcome or counteracted by the foot-pressure on the lever Q. When the plow reaches the ground, the lost motion connection between the two sleeves O and P then permits an independent adjustment or movement on the part of the sleeve 0, and in this way the arm 0 is adjusted upward sufficiently to bring the pivotal point 0 above the axis of the two footlevers-that is to say, just above the center of the land-side axle-thereby permitting the spring to exert its pull or tension along a line above the axis about which the two foot-levers swing; and the spring having thus been adjusted to serve in its capacity of depressing the plow, the plow is then forced to its lowermost position by the combined action of the spring and the. pressure on the foot-lever Q, although it is obvious that the spring is then amply sufficient to put theplow in the ground. Inthis way, as stated, the spring, by reason of the separate mountings for the two foot-levers, is capable of assisting in both raising and depressing the plow, and is'capable of yieldingly maintaining the plow in the ground; and thus the construction not only enables the plow to operate as a stone dodger,

but also enables the spring to automatically effect a quick or sudden increase in its leverage for assisting in lifting the plow. Again, and as stated, complete separation of the two foot-levers by mounting them on two separate sleeves, permits the device for locking the plow in its elevated position to be unlocked without communicating to the plowbeam any of the manual power or pressure necessary for accomplishing the disengagement of the two locking elements from each other.

As previously stated, the capability of the plow to dodge or automatically rise over obstructions is preferably obtained by so adjusting the stop a that the joint or pivotal connection a" remains, even when the plow is down, slightly above the center, or slightly above a line drawn from the pivotal point a through the center of the land-side axle. Thus the joint connection provided between the plow-beam and the land-side axle is always in readiness to buckle or break-joint upwardly against the pull or tension of the spring whenever the plow strikes an obstruction, and in so yielding to preclude all possibility of the breakage or other danger which results when the plow is rigidly and unyieldingly-locked in the ground.

The combined lifting and depressing spring R, by reason of the separate mounting of the two foot-levers, is adapted to be shifted from lifting to depressing position by movement of the depressing foot-lever Q independently of the other footlever. Also, as has been explained, the spring travels from depressing position to lifting position that is to say, it

' shifts at least part of the way from depressing to lifting position, by reason of the movement or adjustment of the depressing lever independently of the lifting lever. In other words, the shifting of the spring from lifting to depressing position, and vice versa, is

accomplished through or accompanied by movement of the depressing lever independently of the lifting lever. I

The object and function of the lost-motion connection provided between the separately mounted portions of the two foot-levers, is simply this: The combined lifting and depressing spring can be shifted from a lifting to a depressing position, and vice versa, through the medium of a certain amount of adjustment or movement on the part of the depressing lever independently of the other lever, and without communicating any power or motion to the plow through the toggle-like or other jointed connection 5 and, further, this lost-motion connection permits of a downward adjustment or movement on the part of the locking element, which is rigid with the depressing lever, before any power or motion is communicated to the plow through the said toggle-like connection; but the shifting of the combined lifting and depressing spring, so that it will pull either above or below the center, as it may be desired to depress or lift the plow, is the principal. object or function of the lost-motion connection; for while its provision makes it somewhat easier to unlock the plow, it is obvious that the locking arrangement would be operative without the provision of any relative movement whatever between the two foot-levers.

With the provision of the combined lifting and depressing spring, the depressing lever is notnecessarily a depressing device in the sense of permitting the plow to be manually pushed into the ground, as the function of the lever is merely to shift the spring, and lower its rigid locking element out of engagement with the lug on the plow-beam, the spring and toggle constituting the means for pushing down on the plow as the plow-point catches and enters the ground and, furthermore, by having the common axis of the le ver stationary, I- find the arrangement is more satisfactory, as the relation of the levers to the drivers position does not change materially, at least as far as convenience of operation is concerned.
